interesting question – bbpress will add the default role you set in forums settings, so if you set this to participant this would sort the majority of users out from a forum perspective.

Which then makes this more of a wordpress question – in essence you could set up the users manually and click to not send them emails, so they would be on the live site when you transfer, but then of course they wouldn’t know their password, so it is a bit of a catch 22 !
